“…It agreed with the highest values for the anthocyanin content found in these two grape varieties for soluble solid contents, expressed as ºBrix, of 22.2 TABLE 1 (CONTINUED) and 19.4 respectively (Navarro et al, 2008). Furthermore, the higher anthocyanin concentration in Monastrell grapes was reported for soluble solid contents comprising between 20.4 and 24.0 ºBrix (De la Hera Orts et al, 2005).…”

The phenolic composition and extractability indices of grape berries play a key role in assessing red wine quality because the relationship between grape phenolic maturity and wine phenolic composition is well known. In this work, grape quality indices were determined in Nebbiolo grapes from two growing areas of Langhe (South Piedmont), at different stages throughout the ripening process in six consecutive years (2004 to 2009), with the aim of evaluating the ripening-and growing area-related changes in the grape indices separately. The effect of vintage was also investigated. Ripeness data were compared with analogous data determined in Nebbiolo grapes grown in the Carema area (North Piedmont). The vintage effect far outweighed any changes in the grape indices introduced by the ripening stage, even those arising from differences in the production area. In the Langhe and Carema zones, the average berry mass, pH, total acidity, total anthocyanins extractable at pH 3.2, total flavonoids and non-anthocyanin flavonoids extractable at pH 1, and the seed maturity index were seasonally dependent. The more ripening-affected parameters were the technological ones. This work highlights the importance of determining the phenol extractability, since it provides relevant information that allows improved management of the maceration stage.

“…In relation to the evolution of total polyphenols during grape ripening, the maximum accumulation was reached when the soluble solid content was higher than 19.4 ºBrix for the Bobal, Tempranillo, Cabernet Sauvignon and Crujidera varieties (Navarro et al, 2008).…”

“…Samples of Tempranillo and Bobal leaf were collected at the end of July (2008-2011) when signs of grape veraison emerged, since this phenology stage was the most adequate to assess the nutritional status of grapevines (Navarro et al, 2008). Foliar N, P, K concentrations in the Bobal and Tempranillo vines (Table 4) fell within the ranges of the mineral nutrients considered optimal for adequate grapevine growth and are similar to those measured in four V. vinifera cultivars (Navarro et al, 2008).…”

Cover crops may improve vineyard soil properties, grapevine nutrient status and berry composition, however, factors such as cover crop type, annual rainfall, climate and irrigation may change their effects on vineyards. From 2008 to 2011, the effects of a non-permanent cover crop and two pruning techniques on soil as well as vine nutrients and grapevine performance of two vineyards (cv. Tempranillo and cv. Bobal) were evaluated. For that purpose, two legumes were sown in inter-rows of hand-pruned vines in February and were tilled at flowering.Soil tillage, or cover cropping, was combined with either light pruning or severe pruning to study foliar nutrient variations. Soil N, P, K and total organic carbon (TOC) were determined in samples taken from the Ap1 horizon in January prior to vine pruning. Foliar N, P, K contents

“…With respect to sampling time, different papers propose two phenological stages: end of flowering or fruit-set, and/or veraison. For instance, Failla et al (1995) used the leaf blade at flowering and veraison; Navarro et al (2008) analyzed the leaf blade at veraison; García-Escudero et al (2002) and Wolpert & Anderson (2007) chose flowering and veraison phenological stages analyzing both leaf blades and petioles separately; Christensen (1984) and Robinson (2005) analyzed petioles at flowering, while Delas (2000) used petioles at veraison.…”

An adequate nutritional state of a crop can be kept by means of a well-designed fertilization plan based on the assessment of the nutrient availability throughout the growing season. The objective of this study was to determine the reliability of leaf blade and petiole diagnosis and the period of validity of their references at both flowering and veraison by means of systematic monitoring throughout the complete growing season. The study was carried out in two plots planted with Vitis vinifera L. cv. Graciano within the AOC Rioja (Spain). Blades and petioles were collected throughout a growing season (2006) and total N, P, K, Ca, Mg, Fe, Mn, Zn, Cu and B concentrations were analyzed in both tissues. Results suggest, in general, that petioles have higher variability and lower analysis reproducibility than blades. Therefore, blade could be a more appropriate tissue to evaluate N, P, K, Ca, and Mg at both flowering and veraison in this variety. Micronutrients in blade and petiole showed different variability behaviour in each of the vineyards studied, therefore, based on our results, it was difficult to determine which one could be the best tissue for the nutritional diagnosis of the 'Graciano' variety. Seasonal changes of nutrient concentration in both tissues also confirmed the need for reference values for each tissue and each phenological stage.Additional key words: nutrition; grapevine; leaf analysis; nutritional references.
